Met a girl on vacation. Not sure if just one time thing or could be more?

I was in Hawaii for a week and I met a girl who was also on vacation there. We met up and went to a bar in Honolulu and had drinks and made out. I don't kiss and tell so I'm not gonna go into more detail but we got each other's numbers and she never texted me back after the night we hooked up. Was it just a one time thing or is there potential for a relationship?
